APPARATUS FOR PREVENTING HORSES FROM CRIBBING.

SPECIFICATION forming part of Letters latent No. 464,854, dated December8, 1891.

Application filed March 13, 1891- Serial No. 384,911. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN CHRISTESEN, a subject of the King of Denmark,residing at Hav' erhill, in the county of Essex and State ofMassachusetts, have invented a new and use ful Improvement in Apparatusfor Preventing Horses from Oribbing, of which the following, taken inconnection with the accompanying drawings, is a specification.

Horses known as cribbers are usually in very poor condition, by reasonof their losing the grain out of their months when they open it to seizethe crib. Thus the grain is wasted and the horse impoverished.

The object of my invention is to produce a device that can be applied tocribbing horses to prevent them from biting the crib.

The invention consists of two frames of horseshoe form arranged onewithin theother, the outer one being provided With pins or studs and theinner frame with openings through which said studs pass, the twoframesbeing held together at their upper ends by screws passing through slotsin the outer frame, and the inner frame is kept in its normalposition-that is, on a line with the points of the studs-by means of aspring, as hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a front viewof a device for preventing horses cribbing, embodying my invention. Fig.2 is a vertical section through the same. Fig. 3 is a horizontal sectiontaken on line a: at of Fig. 1.

A represents the outer and B the inner frame, which are both bent to ahorseshoe form, so as to fit around the throat of the horse. The

. two frames are connected together by means of screws 0, that passthrough slots D, formed in the sides of the outer frame.

In the center of the lower portion of the frame A is formed a hollowboss A, in which is secured a pin or stud E, around which is placed asmall spiral spring F, the upper end of which bears against a collar B,formed on the inner frame B. To the frame A, on each side of the stud E,are also secured other studs E E. The inner frame is formed with slots bb, through which the studs pass, the ends of the studs being on a linewith the inner side of the frame B when the latter is in its normalposition, as shown.

To the upper part of the frame A on one Upon this strap I prefer toplace a wide piece of leather I, that can be adjusted to any requiredposition, so as to fit on the horses neck.

In applying the device to a cribbing horse, the inner frame B is placednext to his throat, the strap H passed over his neck and secured bymeans of the buckle G. Now when the horse is eating his food only thesmooth surface of the frame B is in contact with his throat; but shouldhe attempt to bite the crib he would arch his neck, and the muscles ofthe neck would be expanded, thus causing the inner frame B to be forceddown and the points of the pins or studs E to come into contact with histhroat, and the moment he feels them he will shift his head to itsproper position.

It will be seen that with this apparatus a horse is prevented fromcribbing and sucking wind, and he will swallow what corn he has takeninto his mouth, thus forcing him to con sume his food, and therebypreventing waste.

What I claim as my invention is 1. A device for preventing horsescribbing, consisting of an outer frame having a hollow boss in thecenter of its lower portion, a pin or stud secured in the bottom of saidhollow boss, and pins or studs on each side thereof, an inner framehaving a collar in the center of its lower portion, through whichthe-stud in the hollow boss passes, and slots on each side of thecollar, through. which the other studs on the outer frame pass, the twoframes being held together by screws working in slots in the outerframe, the said frames being kept apart by a spiral spring, the lowerend of which bears upon the bottom of the hollow boss in the outer frameand its upper end against the collar on the inner frame, substantiallyas set forth.

2. In a device for preventing horses cribbing, the combination, with anouter frame A, having a hollow boss A, a pin or spur E, secured in saidboss, pins or spurs E on each side thereof, and slots D inthe sides ofsaid In testimony whereoflhnve signed my name frame, of an inner frameB, having a collar to'thi's specification, in the presence of two 10 Band slots b, the screws G for connecting subscribingwitnesses, on this15th day of J anthe two frames together, the spiral spring F, nary, A.D. 1891.
